- Executive summary:
A study was conducted according to Richtlinie 92/69/EWG to determine the melting point of the test item. The sample was placed in a vessel and placed in the cooling bath. Dry ice was added until the temperatur was 20 -25 °C below the sample temperature and the sample was stirred. Stirring was stopped after the sample crystallized. The temperature increase was monitored. The maximum temperature corresponds to the melting point. The melting point of the substance was determined to be -40 °C at 1013.25 hPa.
Reference
After the preliminary determination of the freezing point the measurement was repeated three times.
| Measurement 1 | -39,5 °C |
| Measurement 2 | -40 °C |
| Measurement 3 | -40 °C |
Description of key information
The melting point of the substance was determined to be -40 °C at 1013.25 hPa.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
